IMPROVED MACHINE FOR SC REWING ON THE SOLES AND HEELS OF BOOTS ANDSHOES.

Specification forming part of Letters Patent-No. 37.201. dated Decemberlti. ism-z.

To all whom i t may concern:

Be it known that LOUIS JULEs SELLIER, deceased, did invent new anduseiul improvements in machines for screwing on the soles and heels ofboots and shoes and other articles admitting of being screwed together,of which.

heels of shoes and boots are composed, and

also the ends and seams of straps or belts, hose-pipe, harness, and thelike articles, by means of a screw which is cut in a continuous mannerby the said machine, and immediately, while being cut, is screwed orentered into the material to be united and riveted thereon, thus tirmlyuniting the dilTerent layers of material. The machine, such as it hasbeen contrived after numerous experiments with a view to producing thebest practical results, is fully represented on the annexed sheet ofdrawings, where-- Figure 1 is a full perspective view of the machine;Fig. 2, a vertical section of the headstock of the machine; Fig. 3, ahorizontal sec tion of the same; Fig. 4c, a side elevation of the noseof the machine as used for belts and straps, harness, &c.; Fig. 5,a planof the rack and cutter for severing the wire after it has been screwedhome; Figsti, 7,8,detached views of the contrivance for allowingthe feedapparatus to rise and take in a fresh length of wire by opening thebisected nut or movable step in which the guide-screw works;"Fig. 9,sectional plan of another device for accomplishing said purpose; Figs.10,11, 12, plan, end, and side elevations of holders or bearers used foruniting the ends and seams of belts or straps, and of similar articles.

In thefollowing description the same letters of reference stand for thelike parts.

A is the treadle or pedal for giving the pressnrerequired for bringingand holding together the (lifi'erent layers of material in the act ofscrewing, theoperator putting his foot on the pedal and setting theshoe, &c., under the nose of the machine, thus allowing him to regulatethe pressure according to the nature of the. material; B, connecting-rodorpitman; O, balance-weight; D,pressure-lever; E, guide; F, screw forraising or lowering the apparatus by means of a winch-handle; G, nut andslideblock; H II, standard and base for same; I I, friction-plates forvarying the lateral inclina tion of the apparatus; 1, bolts screwed intothe fixed plate I and working in circular segmental slots provided inthe movable plate I 1', trunnion; J, dividing head or nose of apparatus; K, head-stock; L M, tube and hollow ball for receiving the scrapsproduced by the chasing of the wire. The ball is made de' tachable fromthe tube bynieans of a set-screw for the purpose of emptying. N, leverforacting on rack for cutting off the screw; 0, pivot of said lever; P,frame; Q, bisected or open ing nut or movable step in which theguidescrew Rworks S,standard, and Sguidc-tube for conducting the wireblank S; T, bevelgear for operating the screw; U, bearing for the smoothspindle part of the hollow'guidescrew R; V, coiled spring for raisingthe hollow screw R whenever it is released from its nut Q; W, table ofthe machine.

In'Figs. 2, 3, 4;, and 5,00 is the cutter for chas ing the brass orother wire as it enters the apparatus. This cutter can be set so as toout either deep or shallow threads by means ofthe inclined slot 1) andset-screw c. d is the cutter, chisel, or graver for cuttingoift'the'wire as near as possible to the surface of the screwed arti clewhen screwed home. This chisel is firmly attached to the cutter-bar e,which is worked by the lever N, Fig. 1, by means ofa rack and pinion, O.The shape of the chisel a is shown in cross-section at Fig. 2, and issuch as to cut off the wire in the manner of an inverted V, which causesthe wire on to flatten out and rivet on the lowest layer fthe materialwhen said end reaches and meets the iron last by the screwing pressure.The coiled springfat the rear of the cutter-oar c is for drawingback thesame when the lever N is released; g, dovetail for inserting the upperpart of the headstock; .h h, recesses in thenose for receiving the stampof each preceding screw, thus acting as a guide for obtaining an equaldistance between each screw and the next following.

In the machine as intended for screwing the adjustable screws l 1, sothat by turning the end of the rotl I. made to enter the nut probyturning the handle 8 to the right, the not heels and soles of shoes,850., I use a last-hold- I or, on which the last and shoe, &c.,-isfixed,as shown at Fig. 1.

i is a. movable or loose bed-plate, on which three pillars, k 7c 70',are mounted. The two outer pillars-Zr 7c", are tapped so as to fit onpillars on. these screws by means of a key, at, they may be raised orlowered to the proper height. The middle pillar, k, hasa swivelingconnecting -joint, I, which, by means of its screwed end, is made toenter a not provided for that purpose in the last. The pillar k isterminated by a point or spike enteringthe last. The pillar k isterminated by a fork or cradle to receive the front part of the vamp oithe shoe. The shoe having been properly set on the twoextreme pillars 7c7c, and t hescrewed videdin the last on ,which the shoeis mounted, asshown on the drawings, the middle pillar, k, is worked by the bevel-gearn n, provided at its lowerpart, and the shoe firtnly drawn down on-theresting-pillars k k" by screwing. The iroperinclinationis giventothelast-holder during the operation by means of a wedgeshaped piece ofwood or its equivalent to be inserted under the base-plate i z. The lasthas to be shod with iron all round on its sole and heel part, so as tocause the screws tohe riveted, as before described.

IWhen the machine is u ed for belts or straps or other large work thefront part or nose of the machine J, Fig. 1, is made longer or moreprojecting, as shown at Fig. 4, by placing the point 0 larther back anddispensing, if necessary, with the tube and ball L M, Fig. 1. In thatcase I also make the nose J convex on its under side, instead of beingflat, as for screwing shoes. The holder for this kind of work is shownatFigs. 10, 1 1, 12." 0 is a smooth convex plate mounted on'a suitablestandard, 7; q q, parallel rods for an adjustable guide, a- 1', to slideon.

The first mode I use for throwing the guidescrew Rin and out ot'gear,for thepnrposes hereinbel'ore stated, is shown at Fig, 9 in horizontalsection. In this plan the two halves of the nut or step c o are made toswivel about a pin, 2, and opened and closed by the agency of a spring,t, cam y, and levers. Another mode for throwing the LILI'CWR in and outof gcaris shown at Figs. 6, 7, and S, and also at Fig. 1. a is a handlekeyed on a spindle, t, which runs in bearings provided in thebracketaand the the first half, o, of the bisected nutor movable step c '0.Through these halves a a pass two screws 1010, the first halves, 'w u,of which are rightthreaded and the second halves, w 10, lett-threaded.Th'csc screws are set in motion by the wheel 3 gearinginto pinions .2Thus,

or' step an is opened and the screw ltis allowed to rise suddenly underthe action of the spring V, Fig. 1, in order to take in a fresh lengthof wire. By turning the handles to the left the not or step is tightenedon the said screw R, so thatbyturning the handle T the screw R becomesactive again for screwing, the fresh length of wire having previouslybeen clamped, as hereinafter described. A suitable stop is provided onthe bracket u for limiting the rotation of the handle s.

The details of construction of the hollow guide-screw R are shown atFig. 13, re-presenting apiece of wire, S, passing through the hollowcoreof the screw. Figs. 14 and 15 are elevation and plan of the collar fortightening the wire; R, screwed portion a, smooth portion, having aslot, 1), into which fits akey fastened in the boss of thedriving-pinion, Fig.1; 0, hexagonal or square end of the screw, havingtwo opposite openings, d (1, into which the clamping-pieces e e arefitted f, collar; 9, screw, which the operatorworks by means of a keyfor nnclatnping the wire when the whole length is screwed and clampingit again after the guide-screw R has been released and a fresh length ofwire taken in; h, screw for fastening the coll'arf'; i, collar fortightening up the clamping-pieces e c. r r, Ftg.2,is an adjustableguide, fixed on the under side of the nose for regulating the distanceat which the screws 4 have to be run in front the edge of the material.l

When it is desired to operate the machine. for screwing on soles theshoe is lasted as usual, the last used, however, being shod. all roundwith iron. in order to cause the screws to be riveted as they emergefrom the sole. The last as used for this inachine-isalso provided with ametallic nut, to receive the screw 5 of the last-holder above described.The shoe or boot having thus-been secured on the last holder, as shownat Fig. 1, the screwing operation may commence. But I would here observethat for common work the shoe last and last holder may be dispensedwith, and an arm may be used, having th shape of a beak-iron. Asufficient lengthfi' wire, S, having been inserted in the tube S, andclamped, the whole apparatus is set to .the proper altitude by means ofthe screw F and the nut and slide block G. The working end of theapparatus is then set to the proper lateral inclination by turning itabout the trunnion 1' and the friction-plates I 1,'so that the screwshall enter perpendicular to the bottom of the last, whatever may bethe'curvatu e at any particular point, this variable inclination being oneof the essential features of the machine. The-operator next applies thenecessary pressure to the sole by pressing his foot more or less on thepedal,

A, and runs the screw in by turning the bandle T tmtil the screw meetsthe iron bottom of the last, which will be readilyt'elt by the operator.The pressure exerted by the nose of the machine throughout thisoperation is a very essential feature, as it prevents the screwseparating one layer from another, and 'espe cially obviates the risingof the sole when the screw meets the last. The operator then pulls thelever N, by which the wire is cut ofl', shifts the last-holder, andcontinues screwing until the length of wire clamped in is used up, when'he releases the clamping apparatus f g h, opens the bisected nut 11 'v,and the spring-V draws up the guide-screw B, so as to take in a freshlength of wire, which is clamped as before, 8:0. The operationsdescribed are continued until the whole of the sole has been sewedon.

The clamping apparatus above described may be modified in various ways,and may be made partly self acting. The scrap-receiver L M may bedispensed with entirely, and instead of the balance-weight c a springacting upon the treadle A may be used.

Having thus described the nature of said improvements invented by saidLOUIS JULES SELLIER, deceased, I claim- 1. Constructing and mounting themachine in such a manner that any required pressure may be produced onthe shoe at the will ot'the operator while the screw is entering thesole, and instantly stopped after the point. of the screw touches theiron last, substantially as and for the purpose described.

2. In combination with a machine for cutting and inserting screws inboots and shoes, an elevating and depressing apparatus, as shown at F GH, Fig. 1, by means of which the machine can be elevated or depressed,as required, as in passing from the heel to the shank of the shoe, whichapparatus also admits of placing the machine-in-such a position that thescrew may enter the sole at any rrequired longitudinal angle,substantially as described.

- 3. Connectingtheinachinetothedepressinglever D, as shown at 1' I 1 I1', for the purpose of inclining the machine to the rightor left, sothat the screw may be entered at any required lateral inclination. 4. Incombination, the elevating and depressing apparatus F G H, with theconnecting-joint I l 1' I I, for the purposes set forth the screw nearthe sole as soon as screwed home.

8. The triangular section of the cutter 11 shown at Figs. 2, 2, and 3,leaving the lower ends of the screw in the shape of an inverted V, forthe purpose of spreading and riveting on the last.
